java程序设计？

下面是BankAccount类的代码：

public class BankAccount {

  private String name;

  private double balance;

  private int year;

  private double rate = 0.01d;

  public String getName() {

      return name;

  }

  public void setName(String name) {

      this.name = name;

  }

  public double getRate() {

      return rate;

  }

  public void setRate(double rate) {

      this.rate = rate;

  }

  public double getBalance() {

      return balance;

  }

  public BankAccount() {

      this.balance = 10d;

      this.year = 1;

  }

  public BankAccount(double balance, int year) {

      this.balance = balance;

      this.year = year;

  }

  public void save(double balance, int year) {

      this.balance = this.balance + balance;

      this.year = year;

  }

  public void fetch(double balance) {

      this.balance = this.balance – balance;

      this.year = 0;

  }

  public double calcTotal() {

      return this.balance * this.rate * this.year + this.balance;

  }

}

下面是BankTest类的代码：

public class BankTest {

  public static void main(String[] args) {

      BankAccount account = new BankAccount(1000d, 3);

      account.setName(“Tom”);

      account.save(2000d, 3);

      System.out.println(“该账户的姓名：” + account.getName());

      System.out.println(“该账户的存款额：” + account.getBalance());

      System.out.println(“该账户的总金额：” + account.calcTotal());

  }

}

下面是运行结果：

麻烦您看一下，是否能够满足要求。

大哥~~我还回答了你另一个“编程题”的问题（），运行过了，没问题的，你记得处理那个问题啊~~^_^呵呵……

这个Java程序设计题怎么做

DecimalFormat df = new DecimalFormat();

df.applyPattern(“0.00”);

double p = 160;

double w = 1000;

double d = 0;

Scanner sc = new Scanner(System.in);

System.out.print(“请输入任意s值：”);

double s = sc.nextDouble();

if (s 0 s 250) {

d = 0;

} else if (s = 250 s 500) {

d = 0.02;

//System.out.println(s);

} else if (s = 500 s 1000) {

d = 0.05;

} else if (s = 1000 s 2000) {

d = 0.08;

} else if (s = 2000 s 3000) {

d = 0.1;

} else if (s = 3000) {

d = 0.15;

}

double exp = p * w * s * (1 – d);

System.out.println(df.format(exp));

JAVA程序设计题（很简单的）

你的题有很多错误，我给你改了一下。

1.设变量i和j的定义如下，试分别计算下列表达式的值：

int i=1; double d=1.0;

1题 35/4 [8]

2题 46%9+4*4-2 [15]

3题 45+43%5*（23*3%2）[48]

4题 45+45*50%i– [45]

5题 45+45*50%（i–） [45]

6题 1.5*3+（++d） [6.5]

7题 1.5*3+d++ [5.5]

8题 i+=3/i+3 [7]

程序阅读题

1给定如下代码，写出程序运行结果

class Example{

public static void main(String arges[]){

int i=0;

do{

System.out.println(“doing it for i is:”+i);

}while(–i0);

System.out.println(“finish”);

}

}

结果如下：

doing it for i is:0

finish

2 阅读程序段写出执行结果

for(int k=1;k=5;k++){

if(k4)break;

System.out.println(“k=”+k);

}

结果：

k=1

k=2

k=3

k=4

3试写出下列程序段循环的运行结果

int i=1;

while(i10)

if(i++%2==0)

System.out.println(i);

结果：

3

5

7

9

操作题

求1!+2!+…+10!

public static void main(String arges[]){

long sum = 0;

for(int i = 1; i = 10; i++) {

long s = 1;

for(int j = 1; j = i; j++) {

s *= j;

}

sum += s;

}

System.out.println(“sum = ” + sum);

}

求100之内的所有“完数”。完数是指等于它的因子和的数。例如：6=1+2+3，6=1*2*3，则6是一个完数

public class wanshu{

public static void main(String[] args) {

for(int i = 1; i = 100; i++) {

if(fun(i)) {

System.out.println(i);

}

}

}

public static boolean fun(int num) {

int sum = 0;

for(int i = 1; i num; i++) {

if(num % i == 0) {

sum += i;

}

}

return num == sum;

}

}
